B NNNNNN O R CARL BUSH, OF MA'ITQON, ILLINOIS, ASSIGNOR OF ONE-HALF TO FRANK L. WALTERS, OF MATTOON, ILLINOIS.

BEADIN'Gr-TOOL RETAINER.

T 0 all whom it may concern:

Be it known that I, CARL BUSH, a citizen of the United States, residing at Mattoon, in the county of Coles and State of Illinois, have invented new and useful Improvements in BeadingTool Retainers, of which the following is a specification.

This invention relates to tools, particularly to attachment therefor, and has for its object the provision of a rubber ring adapted to be engaged upon the shank of a beading tool such as is used on boiler fiue work for upsetting the ends of the tubes passing through the flue sheet, the purpose of the ring being to prevent the tool from slipping through the operators fingers and being forced into the tube in the event that the tool should slip off the bead, as frequently occurs. Tools of this character are operated by means of a pneumatic hammer and the tool is held within the fingers of the operator. In case the tool slips off the bead it generally follows that the tool slips through the operators fingers and has sufficient momentum that it will enter a flue being beaded and become lodged therein so that its removal is impossible even by use of the hook commonly employed for the purpose. The loss ,of these tools is a very serious source of expense and it is with these facts in view that the present invention has been designed which contemplates the provision of a ring which is calculated to strike against the operators fingers and prevent the tool from slipping.

lVith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which- The figure shows a perspective view of a beading tool engaged within an operators hand and showing my retaining ring in position.

Specification of Letters Patent. Patented J 2% 1922 Application filed July 16, 1921.

Serial No. 485,333.

Referring more particularly to the drawings, the letter A designates a heading tool of the ordinary Wellknown type which includes a stem B which receives the impact of the pneumatic hammer or which fits into the so-called pneumatic gun, and which further includes the working end C which is used for making the bead upon fines or tubes.

In carrying out my invention I provide a ring 10 of flexible rubber which is slidably engaged upon the tool A but which fits snugly thereon so as not to become accidentally displaced. It is to be noted that this ring is to be placed at any desired point along the tool though in actual practice it is preferable to locate it comparatively near the stem 13, as shown in the drawing.

In the use of the tool it will be seen that in case the working end C should slip off a bead being formed the tool cannot slip into the tube or fine as the ring 10 would naturally strike against the operators fingers and consequently cause the tool to be retained within his hand.

[From the foregoing description and a study of the drawing it will be apparent that I have thus provided a very simple and which will efiiciently operate to prevent loss of heading tools and which will consequently be a great time and money saver.

Having thus described my invention, I claim:

1. In combination with a heading tool, a ring of flexible material disposed upon the shank of the tool at a selected location and frictionally gripping the tool shank.

2. A retaining device for beading tools adapted to receive impact from a percussion device, comprising a rubber ring disposable upon the shank of a tool and frictionally gripping the same at a desired location.

In testimony whereof, I afiix m signature.
